Methodsof Payment
SilcoTek accepts the followingpaymentmethods.
Galling can occur when twoparts of similar
material are connected under compression
and the heat generated “coldwelds” the parts
together. Customers have observedGallingwhen
twoSilco’d treated compression fittings or NPT
fittings are assembled. For that reasonSilcoTek
does not recommend coating the nuts or ferrules
from compression fittings and recommends
that the coating either be removedwithScotch
Brite or Teflon tapewhen twoNPT fittings are
connected. Galling has never been reportedwhen
a non coated andSilco’d coated fitting ismated.
If bothmatingpartsmust be coated, thenSilcoTek
recommends using anti Seize compoundsmade
fromSilver, Moly or Nickel: For sample cylinder
applications refer to the instructions pertaining to
the use of Teflon tape on the valveNPTprior to
installation
